12m deep and descending the slope that we must take a small gorgonian. There lives a pygmi animal! That is a tiny seahorse just a few years ago was not known to us.

My heart pounding, waiting for the meeting. We are a small group, only 3 divers with cameras to take us the memory of so dear creature of the sea. We finally arrived! Other group is already there. I hear a several times –ooooh!

Closely look more….I spend three seconds, like a target Reaches the proper definition, in my retina Appears the shape of the tiny seahorse. 3 more flashes are triggered in an instant. I prepared my camera to frame the seahorse while 3 or 4 more flashes illuminate the gorgonian. I see the tiny seahorse hide Among the branches of gorgonian: shy, scared of much attention as a “superstar”.

I split from the group a few meters. The flashes are like lightning illuminating gorgonian in a storm, the tiny seahorse. After a few minutes, the divers go in search of another goal. Then I walk slowly, breathing calmly. Upon arrival, a cloud of fine sand is in suspension. In the framework of the gorgonian dive guide shows us a point. Just part of the gorgonian differs: the same color, the same texture. The tiny seahorse still there, in the gorgonian by grabbing its tail.

I do not even try to make a picture. I stood there looking at him a few seconds. Is really tiny, perfect camouflaged in the gorgonian. Seems to be a ” pregnant” male. I still watch a few seconds…I’m finally slowly in silence I go…only my bubbles left behind. And I think, maybe tomorrow I take the picture, quietly and without pressure. Quietly, without raising the fine sand without disturbing you.

So, you Have to Know That there are seven pygmy seahorse species. In Lembeh Strait You have the opportunity to see lot of them.

To be a seahorse pymy you must to see:

–A single gill opening on the back of the head, instead of two on the sides.

–Males Their inside trunk, instead of in a pouch on the tail.

When you dive for the first time in Lembeh strait (also occurs after 100 dives) we see very clearly that there is a high biodiversity. This concept of “biodiversity” is often unclear, perhaps because the scientific language is a bit complicated. The cultural issue is that many people understand that refers to the presence of many different species. This is true but not completely, the ” biodiversity” refers both: to the fact that in a place there are many different species and while there each present a high number of individuals.

To explain this concept in a more clear way we can take the example of a network of underground stations. More diverse is that which has the greatest number of lines (London in UK) as many other network stations to submit few lines and few stations (Valencia in Spain). You can see two pictures of subway lines with opposite diversities.

Now we know biodiversity, is time to ask how it happens. This is the big question! Evolution always exists, because it is simply a mutation, which literally means “change”. Change in genes that are often reflected in morphology, behavior, etc… all the changes in the individual. Natural selection works like a filter survival in which only those who survive are played, and thus increase their genes in the population of a species. When changes are allowed survival ends cause the creation of a new species, increasing the Biodiversity.

Another important aspect is that this can only be understood if we think the evolucion in thousands, millions of years. At that time scale is where a small genetic changes that are repeated and remain will become big differences. There are other aspects that help make it happen: physical isolation of the place, ecosystems variety, or more or less stable envriontment conditions over long periods of time.

Darwin and Wallace explained the theory of evolution long time ago. With modern science has been able to verify the veracity of this. Wallace got his information traveling through the British and Dutch East Indies. He discovered a line between wildlife Australian Asia, call the wallace line. And this leaves the island of Sulawesi and Lombok, and West-North Island Bali, Borneo and the Philippines. One of the geological events that explain this line is the change in the water level of the sea due to periods of glaciation. (you can see a short Video here).

To finish, the Lembeh strait is a place that has always been isolated from the rest, and is in an isolated area where conditions have occurred for life has exploded in variety of creatures that look for ways to survive. Like most litoral ecosystem, species that housing here has been specializing in camouflage, in hiding, in defending themselves with poison.

Last week we were very busy. Full house in KBR. Guests from China, Hong Kong , USA , Korea.
